Saving for a child's future college costs works similarly to any other long-term savings goal — consistent contributions combined with investment growth over many years can build to a meaningfully larger sum than the raw contributions alone.
Enter your current savings balance, planned monthly contribution, expected average annual return, and years remaining until college enrollment, and this calculator projects your ending balance using monthly compounding, similar to a 529 plan or other education savings account.
Starting earlier has an outsized impact on the final balance because of how much longer the money has to compound — even modest monthly contributions started early in a child's life can meaningfully outpace larger contributions started just a few years before enrollment.

Frequently asked questions
What return rate should I assume for a 529 plan?
It depends heavily on your specific investment allocation within the plan — many 529 plans offer a range of options from conservative to aggressive, so use a rate consistent with your actual chosen investments.
Does this account for the tax advantages of a 529 plan?
No, this projects raw investment growth only; 529 plans often offer tax-free growth and withdrawals for qualified education expenses, which isn't factored into this straightforward growth projection.
